Paging and Network Selection Techniques for Wireless Communication

1. A wireless communication method, comprising: transmitting, by a network node to a communication node, multiple sets of paging configuration information, wherein each set of paging configuration information includes a service type information that describes a type of network service, and wherein each set of paging configuration information includes one or more paging related information; receiving, by the network node from the communication node and prior to the transmitting, a first message that indicates that the communication node supports multiple paging configuration; and transmitting, to a core network and after receiving the first message, a second message that indicates that the communication node supports multiple paging configuration, wherein an Access Stratum (AS) layer of the communication node indicates at least two sets of paging configuration information to a Non-Access Stratum (NAS) layer of the communication node, wherein the NAS layer selects, from the at least two sets of paging configuration information, a Paging Control Channel (PCCH) configuration information associated with one set of paging configuration information, wherein the NAS layer indicates the selected PCCH configuration information to the AS layer, and wherein the AS layer detects paging based on the selected PCCH configuration information.

2. The method of claim 1, wherein the service type information includes a Network Slice Selection Assistance Information (NSSAI).

3. The method of claim 1, wherein the one or more paging related information includes one or more paging control channel (PCCH) configurations.

4. The method of claim 1, wherein the multiple sets of paging configuration information are transmitted in a system information block (SIB) or a radio resource control (RRC) message.

5. The method of claim 1, wherein prior to the receiving the first message, the network node transmits, to the core network, a third message that indicates that the network node supports multiple paging configuration.

6. The method of claim 1, wherein a same criterion for selecting of a set of paging configuration from the multiple sets of paging configuration information is shared by the communication node and the core network.

7. The method of claim 1, wherein the NAS layer of the communication node indicates one or more allowed slices indicated by one or more Network Slice Selection Assistance Information (NSSAI) to an Access Stratum (AS) layer of the communication node, wherein the AS layer selects, from the one or more allowed slices, a Paging Control Channel (PCCH) configuration information associated with a NSSAI, and wherein the AS layer detects paging based on the PCCH configuration information.

8. A network node for wireless communication, comprising: a processor configured to implement a method, the processor configured to: transmit, to a communication node, multiple sets of paging configuration information, wherein each set of paging configuration information includes a service type information that describes a type of network service, and wherein each set of paging configuration information includes one or more paging related information; receive, from the communication node and prior to the transmitting, a first message that indicates that the communication node supports multiple paging configuration; and transmit, to a core network and after the first message is received, a second message that indicates that the communication node supports multiple paging configuration, wherein an Access Stratum (AS) layer of the communication node indicates at least two sets of paging configuration information to a Non-Access Stratum (NAS) layer of the communication node, wherein the NAS layer selects, from the at least two sets of paging configuration information, a Paging Control Channel (PCCH) configuration information associated with one set of paging configuration information, wherein the NAS layer indicates the selected PCCH configuration information to the AS layer, and wherein the AS layer detects paging based on the selected PCCH configuration information.

9. The network node of claim 8, wherein the service type information includes a Network Slice Selection Assistance Information (NSSAI).

10. The network node of claim 8, wherein the one or more paging related information includes one or more paging control channel (PCCH) configurations.

11. The network node of claim 8, wherein the multiple sets of paging configuration information are transmitted in a system information block (SIB) or a radio resource control (RRC) message.

12. The network node of claim 8, wherein a same criterion for a selection of a set of paging configuration from the multiple sets of paging configuration information is shared by the communication node and the core network.

13. The network node of claim 8, wherein the NAS layer of the communication node indicates one or more allowed slices indicated by one or more Network Slice Selection Assistance Information (NSSAI) to an Access Stratum (AS) layer of the communication node, wherein the AS layer selects, from the one or more allowed slices, a Paging Control Channel (PCCH) configuration information associated with a NSSAI, and wherein the AS layer detects paging based on the PCCH configuration information.

14. The network node of claim 8, wherein prior to the first message being received, the network node is configured to transmit, to the core network, a third message that indicates that the network node supports multiple paging configuration.
